This developer preview includes:
- GraphQL Server — A custom spec-compliant GraphQL implementation. We automatically generate the server from the SDL schema including support for filters w/ boolean expressions, sorting, and pagination.
- Ethereum Adapter — Subscribes to Ethereum events using IPC or RPC and accesses smart contract storage.
- WASM Runtime Host — Executes developer-provided Mappings on WASM using Parity’s excellent Wasmi library.
- Postgres Store — Stores and indexes the transformed data in an entity table in Postgres, which is queried by the GraphQL server.
